HAN D-GRIP FOR GUNS.

Speccaton of Letters Patent.

Patent-ed Nov. i1, 191e.

Application filed October 23, 1918. Serial No. 259,431.

To all whom t may concern:

Be it known that I, CHARLES D. VIpsON, a citizen of the United States, and a resident of Toledo, in the county of Lucas and -State of Ohio, have invented a certain new and useful Hand-Grip for Guns; and I do' hereby declare the following to be a full, clear, and eXact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the Characters of reference Amarked thereon, which form a part of this specification.

This invention is particularly intended for use in connection with rapid fire guns of the Browning type.

rlhe Object of my invention is the provision of a hand grip of the class described, which is capable of being detachably mounted on the barrel and adjacent parts of a gun, which parts become highly heated during a firing of the gun, is light, strong and durable in its construction, and is capable of being subjected to very high temperatures without injury to its parts. Y

A further and important feature of the invention is the provision of a hand grip of the class described, which is adapted to inclose the action slide or plunger of guns of the Browning type, in such manner that the rapid operating movements of the slide or plunger thereof create a forced ycirculation of air through the hand grip to facilitate a cooling of both the grip and the heated parts which it embraces.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of a portion' of a gun of the Browning type with a hand grip embodying the invention mounted thereon, and with said grip and the embraced portion of the gun in central vertical longitudinal section. Fig. 2 is a section on line 2 2 in Fig. 6, with parts removed. Figs. 3, 4 and 5 are cross-sections on the lines 3 3, 4 4: and 5 5, respectively, in Fig. 1. Fig. G is a side elevation ofthe hand grip mounted on a gun with the latter only fragmentarily shown. Fig. 7 is a central vertical longitudinal section of the hand grip embodying the invention. Fig. 8 is la horizontal longitudinal section thereof, and Fig. 9 is a side elevation of the inner shell or lining of the grip.

The grip forming the subject of this application is a species of the invention described and originally lclaimed in my application filed July 23rd, 1918, Serial No. 246,881, and as such species is the preferred embodiment of the invention, the broad claims `are made in the present application.

Referring to the drawings, 1 designates the stock and 2 the barrel of a rapid fire gun of the Browning type. 3 designates the gas cylinder of such gun which is attached to the under side of the barrel and has its interior in connection with the bore of the barrel through its small Ipassage 4. A plunger 5 operates in the cylinder and is connected with certain operating parts (not shown) of the gun mechanism by a slide G, which is connected to the plunger by a stem 7. A frame bar 8 is removably Xed to the stock 1 and extends forward therefrom and has its forward end provided with an olf-set portion 9 that is provided with an opening in which the rear end of the gas cylinder 3 is mounted. These parts are all common to the Browning gun and need not therefore be specilically described.

' The hand grip embodying my invention is intended to embrace the rea-r end portion of the barrel 2 and the adjacent portions of the cylinder 3, slide 6 and frame bar 8 at the point where the gun is customarily gripped when in use or when being carried. This hand grip comprises a lining or inner shell l0, preferably of aluminum, and anv outer shell 11, preferably of vulcanized ber, the inner shell being shaped to adapt it to be slipped longitudinally over the barrel 2, cylinder 3, plunger slide 6 and frame bar 8 with its rear end in abutment with the stock and a shoulder portion of the frame bar 8 with its forwardend set against the under side of the cylinder 3 and forming an airy ment of the rear end of the hand grip with the stock is such as to provide an air circulating space between the sides and top portion of the grip and the stock or 'inclosed portion of the gun.

The shell 10 is substantially U-sh'ape in cross-section with its terminal side edge portion turned inward over the barrel in spaced relation thereto and preferably terminating in spaced relation to each other to form the longitudinal top opening 1:2. The shell 10 is provided with longitudinally spaced cross ribs 13 in its bottom portion which form bearings for Jthe frame bar S and space such bar from the major bottom portion of the shell, as shown in Figs. 1 and 7. The shell is also provided at its forward end portion with longitudinally spaced bea-rings or rests 14C for the cylinder 3, the rear rest being vertically spaced from the bottom of the shell to permit the circulation of air there under.

The outer shell 11 entirely closes the inner shell fitting closely'thereto at its ends and being spaced from the inner shell intermediate its ends to provide air circulating chambers or spaces 15 therebetween. 1t is preferable to slightly contract the bulged side portions of the shell above the bottom thereof, as best shown in Fig. 4;, to better facilitate a firm gripping of the shell by the hand of the operator. t is preferable, but not necessary, to provide the inner shell 10 with longitudinally spaced vertically eX- tending ribs 16, which effect a positive spacing of the two shells at the sides and bottom portions thereof. It is also preferable to extend the ribs 16 up over the inturned edges of the inner shell to provide air escape openings or passages 17 between the .lapped upper edge portions of the respect-ive shells. Air is admitted to the circulating spaces between the shells through a plurality of openings 18 in the lower portions of the outer shell 11 (see Figs. l and G).

The shells 10 and 11 are secured together, in the present instance, by rivets 19 at their ends and by similar rivets (not shown) disposed along the top inturned edge portions thereof through the spacing ribs of the inner shell. The hand grip is secured to the frame bar 8 by a screw 20` and also by a cross screw or bolt 21.

My hand grip when applied to a gun provides an air circulating space lengthwise through the grip around the inclosed gun parts with such space open at both ends and also along its top to the asmosphere. Upon the firing of the gun the rapid reciprocation of the slide 6 within the grip causes a forced circulation of a cooling air through the grip and a consequent cooling of the heated parts, it being understood that after each explosion a portion of the created gas enters the cylinder 3 from the gun barrel in advance of the plunger 5, and drives such plunger rearward. It is found in practice that a considerable current of air is created through the hand grip by the pumping action of the plunger on its slid'e.

In addition to cooling the hand gripk and inclosedparts by the forced circulation of air therethrough the cooling of the grip is also facilitated by the circulation of air between the inner and outer shells 10 and 11 thereof, through the side spaces 15, thus preventing liability of burning the hands of the operator.

It is Vfound in practice that particular advantage is obtained from making the inner shell of aluminum as it not only lightens the handle and provides a strong frame or reinforcement for the outer fiber shell, but facilitates a cooling of the grip over other materials which have been used. It is also found that the use of vulcanized fiber as the material for the outer shell is important,y asfsuch material is a good heat insulator, is Acapal'ile of standing intense heat without charring and cracking, and also of being dipped in water when heated and of being soaked for several hours without cracking or warping. It is also capable of resisting hard knocks and pressure without breaking. `All of these qualities are of kthe utmost importance in a hand grip for fire arms.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts, as it is capable of numerous modifications without departing from the spirit of the claims.
